Frederick C. Kurz d766e82aa1 Changes for vvp/vvp_net.h
"# include  <string>" was added so "Microsoft Visual Studio Express 2015 RC Web" could compile it without error. "static void operator delete[](void*); was preprocessed so "Microsoft Visual Studio Express 2015 RC Web" could link it without error for a function not yet implemented.
2015-07-22 18:02:52 -07:00
Frederick C. Kurz c35f2f8334 Changes to vvp/vthread.cc
"child->delay_delete = 1;" was added, for when building with "Microsoft Visual Studio Express 2015 RC Web" in DEBUG mode, so that pr2909555.v would pass with -strict, otherwise it would cause memory access error will trying to access the previously deleted "child" variable.

Martin Whitaker 97c6339241 Ensure VPI release on net connected to island returns correct value. 2015-07-01 09:00:43 +01:00
Martin Whitaker 8d2149f5aa Further fix for GitHub issue #73 - also handle part selects. 2015-06-30 23:59:00 +01:00
Martin Whitaker e8225bd39e Fix for GitHub issue #73 - allow for island ports in vpi_put_value.
In the special case that a net is attached to an island port, values
driven onto the net via the VPI must go to the functor, not the filter,
so that they propagate through the island.
2015-06-30 21:50:13 +01:00
Martin Whitaker 637fc40dd9 Fix various bugs in vpi_put_value.
When putting a value onto a wire, the value needs to be sent to the
filter, not the functor (the functor may be part of the expression
that drives the wire).

Force and release weren't implemented properly (or at all in the
case of real values). They need to behave the same as the force
and release operations in vthread.cc.
2015-06-26 08:49:41 +01:00
Martin Whitaker dad223316e Fix propagation of unforced bits when forcing a part select.
vvp_net_t::force_vec4 propagates all bits of the forced value passed
to it, regardless of the mask value. I can't see any way to fix this
directly, so instead make sure anything that calls force_vec4 sets
the unforced bits of the passed value to the correct value.

Larry Doolittle b23faff27c Just a few more spelling fixes
Includes some user-visible messages
2015-06-17 08:09:34 -07:00
Martin Whitaker b242663cae Support negedge flip-flops in synthesis and in vvp.
Also extend the support for FF asynchronous set values to vvp and
fix the dff functor in vvp to correctly model asynchronous set/clr
behaviour.

Stephen Williams 05d591ccd6 Fix broken write to log files. 2015-06-03 14:32:04 -07:00
Stephen Williams e6c6f6c81e Use fwrite to write $display output, instead of fprintf
This change makes it safe to write non-ascii characters, which
is an issue when the %u format is used.

Martin Whitaker c75498b1d4 Add -i (interactive) option to vvp.
This forces <stdout> to be unbuffered. This is useful when using the
mintty terminal emulator in Windows (as used by MSYS2 and CygWin),
which identifies as a pipe, not a tty.

Martin Whitaker b6304129fa Fix for GutHub issue #64 - vvp interrupt/continue in Windows.
Windows implements the original UNIX semantics for signal(), which
means you have to re-establish the signal handler each time a signal
is caught.
2015-05-15 22:30:03 +01:00
Martin Whitaker ac4f4cf1a0 Update man pages.
Removed obsolete -m32 and -ivl options from iverilog-vpi man page
and revised description of -mingw option. Also removed duplicate
descriptions of --cflags, --ldflags, and --ldlibs options. Updated
link to main iverilog web page in all man pages.

Martin Whitaker cfbc90812b Enable use of MinGW ANSI stdio routines.
Defining __USE_MINGW_ANSI_STDIO=1 provides C99 compatible printf
and scanf routines, which avoids the need for workarounds for the
various failings of the Microsoft C runtime library.
2015-05-10 11:45:42 +01:00
Martin Whitaker 6a3edc63d5 Fix printf format for size_t values when using 64-bit MinGW.
The Microsoft C runtime does not support the %zu and %zd formats.
Previously these were replaced with %u and %d, but for 64-bit we
need to use %llu and %lld.
2015-05-08 20:20:14 +01:00
Martin Whitaker 45dc13e496 Use uintptr_t/intptr_t when casting between pointer and integer.
The code was using (unsigned) long, but a long is 32-bits in the
Windows 64-bit ABI.

Martin Whitaker e006f9e132 Fix vvp crash when a part select of a wire is passed to $monitor.
When the PV expression is compiled, the parent net may not yet be
resolved, so we may not be able to get its VPI handle straight away.

Martin Whitaker a1630e1d30 Fix for br968.
__vpiVThrVec4Stack::vpi_get_value_int_ was always treating the thread variable
as unsigned, rather than observing the value of __vpiVThrVec4Stack::signed_flag_.
Not sure why this was done - none of the regression tests broke when I changed
this.
